Run this example from the command line with:
node eg/proximity-hcsr04.js
const { Board, Proximity } = require("johnny-five");
const board = new Board();
board.on("ready", () => {
const proximity = new Proximity({
controller: "HCSR04",
pin: 7
});
proximity.on("change", () => {
const {centimeters, inches} = proximity;
console.log("Proximity: ");
console.log(" cm : ", centimeters);
console.log(" in : ", inches);
console.log("-----------------");
});
});
